  • DETAILED DESCRIPTION
  • Referring to FIG. 1, a data center according a first embodiment of the present disclosure is shown. The data center comprises multiple server systems 100, and in FIG. 1, two server systems 100 are shown for an example. The server systems 100 are arranged back to back. Each server system 100 comprises a server cabinet 10, a plurality of servers 20 stacked in the server cabinet 10, and a plurality of fan modules 30 positioned in the rear side of the servers 20. Multiple neighboring servers 20 can share the fan module 30 in the server system 100. In this embodiment, two neighboring servers 20 share the fan module 30.
  • Referring to FIGS. 2 and 3, the fan module 30 comprises a rectangular frame 310 and a plurality of fans 320 rotatably accommodated in the frame 310 in a line. A pair of first rollers 410 extends horizontally from upper portions of two ends of the frame 310. That is, each first roller 410 extends from the upper portion of each end of the frame 310. A pair of second rollers 420 extends horizontally from lower portions of two ends of the frame 310. The first and second rollers 410, 420 have a columned shape. The first rollers 410 are narrower, but longer than the second rollers 420.
  • Referring to FIGS. 4 and 5, the server cabinet 10 comprises multiple pairs of first rails 110 and second rails 120. Each pair of second rails 120 extends from the front side of the server cabinet 10 to the rear side of the server cabinet 10. The sever 20 can slide on the pair of the second rails 120. In this embodiment, each pair of second rails 120 is provided for each server 20, and two neighboring servers 20 share the fan module 30. Therefore, in a range of the height of the fan module 30, there are two pairs of second rails 120 and two servers 20. The fan module 30 is positioned at the rear side of the servers 20 and is perpendicular to the second rails 120 to provide cool air along a horizontal direction for the servers 20. The first rail 110 interconnects the second rail 120, which is at the lower portion of the fan module 30. The first and second rails 110, 120 cooperate to form a rail system 130. The first and second rollers 410, 420 of the fan module 30 are glidingly engaged in the rail system 130. The fan module 30 is capable of sliding on the first and second rails 110, 120.
  • The first rail 110 has an arc shape and curves out and up from a rear portion of the second rail 120. There is a predetermined distance between the rear end of the second rail 120 and the curved position of first rail 110, namely, the curved position of the first rail 110 extends at the rear end of the second rail 120. The cross section of the first and second rails has a substantially “[” shape which includes top and bottom walls and a lateral wall interconnecting the top and bottom walls, leaving an opening oriented to the server 20. The height of the second rail 120 (i.e., the distance between the top and bottom walls of the second rail 120) is substantially equal to the diameter of the second roller 420. The width of the second rail 120 (i.e., the width of the top or bottom wall) is substantially equal to the longitudinal length of the second roller 420. The second rail 120 is configured for fitly receiving the second roller 420 therein. The height of the first rail 110 is smaller than the second rail 120, and is substantially equal to the diameter of the first roller 410. Therefore, only the first roller 410 can slide in the first rail 110, and the second roller 420 having a larger diameter cannot slide into the first rail 110. The width of the first rail 110 is substantially equal to the longitudinal length of the first roller 410. The second rail 120 defines a longitudinal slot in the lateral wall thereof for the first roller 410 extending through when the first roller 410 slides in the second rail 120.
  • As shown in FIG. 5, when the fan module 30 is in a fixing state, the pair of first rollers 410 is engaged in the top of the pair of first rail 110, and the pair of second rollers 420 is engaged in the rear end of the pair of second rails 120. The pairs of the first and second rollers 410, 420 are in a same vertical plane, and the fan module 30 is perpendicular to the second rails 120.
  • As shown in FIG. 6, when the fan module 30 needs to be replaced, the sever 20 blocking the second rails 120 is firstly carried out of the server cabinet 10 along the second rails 120, providing a passage for the first and second rollers 410, 420 of the fan module 30. The fan module 30 is pulled out, the second rollers 420 roll forwards along the second rails 120, and the first rollers 410 roll down along the first rails 110. As shown in FIG. 7, the fan module 30 rolls along the second rails 120 in a horizontal state, until it rolls out of the server cabinet 10 from the front side thereof.
  • In assembling the fan module 30 in the server cabinet 10, the first and second rollers 410, 420 of the fan module 30 roll back along the second rails 120 in a horizontal state. The second rollers 420 are fitly received in the second rails 120. The first rollers 410 insert through the slot of the lateral walls of the second rails 120. When reaching the branching position of the first and second rails 110, 120, the first rollers 410 roll up into and along the first rails 110. The second rollers 420 continue to roll along the second rails 120, and cannot roll into the first rails 110 due to the larger diameter of the second rollers 420. When the first rollers 410 reach the top of the first rails 110, the second rollers 420 reach the rear end of the second rails 120, and the fan module 30 is fixed in the rear side of the server cabinet 10 and perpendicular to the second rails 120. The server 20, which is removed, is then loaded in the server cabinet 10 along the second rails 120.
  • It is noted that, the drawings only schematically show a working relationship among the first and second rollers 410, 420, and the first and second rails 110, 120 for illustrating an exemplary embodiment. An exact dimension or configuration of the first and second rollers 410, 420, and the first and second rails 110, 120 can be designed as desired.
  • FIGS. 8 and 9 illustrate a fan module 30 a, and first and second rails 110 a, 120 a of a server system in accordance with a second embodiment of the present disclosure. A pair of first rollers 410 a is formed on the upper portion of the rear side of the fan module 30 a, and each first roller 410 a is located adjacent to the lateral end of the fan module 30 a. A pair of second rollers 420 a is formed on the lower portion of the rear side of the fan module 30 a, and each second roller 420 a is located adjacent to the lateral end of the fan module 30 a. The first roller 410 a is fixed on the fan module 30 a by a first pivot 401. The second roller 420 a is fixed on the fan module 30 a by a second pivot 402. The first pivot 401 is longer than the second pivot 402. The first and second pivots 401, 402 are capable of rotating around the fan module 30 a. The first and second rollers 410 a, 420 a are round, and the first roller 410 a is smaller than the second roller 420 a.
  • The second rail 120 a is straight and positioned in a horizontal plane. The first rail 110 a has an arc shape and extends up from the rear end of the second rail 120 a. The first rail 110 a and the second rail 120 a cooperate to form a rail system 130 a. Cross sections of the first and second rails 110 a, 120 a are a U shape having an opening at top thereof. The second rail 120 a is wider than the first rail 110 a. The width of the first rail 110 a is slightly larger than or substantially equal to the diameter of the first roller 410 a. The width of the second rail 120 a is slightly larger than or substantially equal to the diameter of the second roller 420 a. Therefore, the first roller 410 a is capable of rolling in the first and second rails 110 a, 120 a, but the second roller 420 a is just capable of rolling in the second rail 120 a. Other characters of the server system in this embodiment are similar to that in the previous embodiment; thus, a detailed description is omitted.
  • When the fan module 30 a needs to be replaced, the lower server 20 is removed from the server cabinet 10 along the second rails 120 a, providing a passage for the fan module 30 a. The fan module 30 a is then pulled out, the second rollers 420 a roll forwards along the second rails 120 a, and the first rollers 410 a roll down along the first rails 110 a, whereby the fan module 30 a is turned from a vertical state into a horizontal state on the second rails 120 a. Finally, the fan module 30 a is removed along the second rails 120 a.
  • In assembling the fan module 30 a in the server cabinet 10, the fan module 30 a is initially oriented in a horizontal state, and the first and second rollers 410 a, 420 a of the fan module 30 a are pushed to roll back along the second rails 120 a. When reaching the first rails 110 a, the first rollers 410 a roll up into and along the first rails 110 a. The second rollers 420 a continue to roll along the second rails 120 a. The second rollers 420 a stop at the rear end of the second rails 120 a and cannot roll into the first rails 110 a due to the larger diameter of the second rollers 420 a. At the same time, the first rollers 410 a reach the top of the first rails 110 a, whereby the fan module 30 a is fixed in the rear side of the server cabinet 10 and perpendicular to the second rails 120 a. The server 20, removed previously is then loaded in the server cabinet 10 along the second rails 120 a.
  • The sever system provided by the present disclosure can assemble or disassemble the fan module from the front side of the server cabinet and only need to remove a single server from the server system. Thus, there is no need to shut down the whole server system when one of the fan modules need to be repaired or replaced, and it is more convenient for the maintenance of the fan module since there is a greater amount of workspace at the front side of the server system.
  • It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the embodiments. The disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
